Industry
General.
In the 1970s and 1980s, industry in the Caucasus was well-developed.
The major industrial sectors were: oil and gas, chemicals and
machinery industries, ferrous and non-ferrous metallurgy, cement,
fertiliser, light manufacturing and food processing.
In the
Soviet period, rapid industrial development resulted in increased
environmental pressures. From 1970 to 1990 overall production, for
example, increased three times in the South Caucasus. However, the
level of industrial development was still less the union average
value. After the USSR was dismantled, industrial production sharply
declined in the Caucasus region, because of the energy crisis and the
break of economic ties between the former Soviet republics. Recently,
some signs of industrial revival have appeared. However, the growth
rate is still insignificant.
In general,
industrial activities are not equally distributed across the region.
Most industrial centres are located in lowland zones along the
railways, concentrated in large cities.
Manufacturing
Sector.
Some of the most important environmental problems in the Soviet
period were connected with manufacturing industries. The Caucasus was
not as heavily industrialised as European Russia, and suffered less
environmental pollution, but the impact of industry on the
environment was not unimportant. Of the heavy industries, oil
processing, chemical, metallurgical, machinery and cement
manufacturing plants were built, which created some of the most
significant centres of pollution. Beginning from the 1970s until the
disintegration of the USSR, the increasing trend of impact on the
environment from stationary sources was observed, in spite of the
fact that a number of environmental legal acts were adopted and
Soviet standards were among the strictest in the world. However, the
lack of law enforcement from the government side and pollution
controls from industry side contributed significantly to increased
emissions into all environmental media.
High pressures on
environment from industry were traditionally due to extensive power
and raw material consumption. Explanations for these can be
attributed to many causes, the basic among them being the
political-economic arrangement of the Soviet Union.
In
general, the major focus was on economic growth and rapid
industrialisation, without proper consideration of environmental
issues. In centrally planned socialist systems, all means of
production were owned by the state. Practically no attention was paid
to the efficiency implications of pricing. State planners set minimal
or no prices on inputs in order to promote industrial development.
Consequently, the Soviet economy was extremely resource-intensive
with economic sectors, including industry, over-utilising natural
resources and polluting all environmental media.
Industrial
production was significantly reduced in the 1990s. At present, some
industrial sectors of industry are not functioning or are in severe
crisis (working at 20-25% or less capacity).
The
fall of industrial production has resulted in some reduction in water
and air discharges and industrial waste generation from stationary
sources. Nevertheless, the reduction of environmental pressures from
industry was not followed by major improvement in the state of the
environment. “Old” sources of pollution, toxic industrial wastes,
heavy metals accumulated in the ground, obsolete technologies and
pollution control equipment remain important factors contributing to
environmental pollution and degradation.
Mining
Sector.
An important factor influencing the environment, both during the
Soviet period and today is open-pit mining operations (non-ferrous
metals, manganese, coal, gravel, sands, quartz sand extraction),
which are common in the Caucasus. Prospects for future development of
extensive mining are likely. Therefore, the mining sector will remain
an important factor affecting the environment. In many places, open
mines are located on household plots and agricultural lands, causing
land
degradation, creation of badlands and development of geo-dynamic
processes. Some of the mines situated at relatively high altitudes
impose a direct threat to fragile mountain ecosystems and affect
lowland habitats downstream from such mines. There are few land
reclamation works, but where they occasionally are, they yield no
results in mountainous areas.Of
particular concern are tailings from extractive and processing
operations. There is a high risk that pollutants from these tailings
may leach into water systems. This often occurs in the regions where
ores are being extracted. Oil and gas-prospecting companies in the
Baku-Sumgayit area and the North Caucasus (Krasnodar, Grozny and
Maikop) form important centres of pollution as well. Since the mining
sector experienced a lower decline than the manufacturing sector in
the 1990s, it is a proportionally larger force in the economy.
- Oil has been of greatest importance for Azerbaijan all through
its history. Evidences of oil extraction on the Absheron peninsula
have existed since the 5th century AD In 1897-1907, the 833 km
long Baku-Batumi oil pipeline was built, which was the largest in
the world at that time (one of the first oil pipelines in the
world was built in Azerbaijan in 1878). In 1901, Absheron was the
largest oil producer in the world (it accounted for over 50% of
the world’s extraction). Before World War II, Azerbaijan was the
greatest oil extracting and supplying region of the USSR, with ѕ
share of total oil extraction. However, this was not followed by
important rise in socio-economic conditions in the republic.
Moreover, the state of the environment has become worse. Current
levels of oil production in Azerbaijan are far below the 70s and
80s levels explained by reduced oil reserves, out-of-date
technologies, inadequate investments, etc. It is noteworthy to
mention that Caspian oil has made the Caucasus a strategic region.
In the
Caspian seashore, the extensive extraction of oil has been conducted
for more than a century. Therefore, its influence on sensitive
aquatoria and densely populated area is quite high. Near Baku oil
has heavily polluted around 10,000 hectares of land. In former USSR
the area of Absheron peninsula was considered the region the most
polluted by oil products, where pollution was 32 times higher than
the background level. In the 1970s, the discharge of polluted water
into the sea was prohibited, but that brought about no major
changes. Wastes, which were neither buried nor utilised, were
disposed of on the shore. Therefore, during storms they returned to
the sea. This had negative impact on flora and fauna.
- In
Chiatura (Georgia) manganese quarries, thousands of hectares of
agriculture lands have been excavated and become useless. As a
result, erosion and landslides have become extensive, comprising a
high threat to settlements. Tailings formed because of ore
enrichment have accumulated in high quantities. Waste-waters with
high manganese concentration have been heavily polluting River
Kvirila.
- Madneuli
(Georgia) non-ferrous metal (copper, lead, zinc and also gold)
mine is one of the largest in the Caucasus. It has been exploited
since 1970s. The surrounding environment is much degraded and
arable lands are useless. Open pit waters of the deposit-based ore
processing plant pollute the Kura river tributaries. In 1992, the
copper content in the Kazretula River was 220 times higher than
legal standard and zinc content was 65 times higher. About
20-30,000 people live in this area. Local agricultural products
(mainly vegetables) are supplied to the inhabitants of the city of
Tbilisi and its surroundings. Air is also polluted by heavy metals
(cobalt, chromium, cadmium, nickel, arsenic, others), where the
amount of dust emitted annually amounts to 31 tons.
- In
Tyrnyauz (Kabardino-Balkaria, the North Caucasus) tungsten and
molybdenum has been extracted and enriched since the Soviet times.
After the short break, the industrial activities were re-newed
here in 1994, although adequate environmental actions were not
undertaken. Consequently 5,527 t suspended substances, 0.1 t of
molybdenum and 0.07 t arsenic flow into the Baksan River annually.
